Blendo Adroit – Continuous gravimetric blender and extrusion control

Designed to blend pellets in extrusion processes where dosing accuracy and a homogeneous dispersion of additives are strictly required. Unaffected by vibrations, BLENDO ADROIT has been designed to be easily mounted directly on the extruder throat to replace the conventional feed hopper or for mezzanine mounting. Available from 2 to 6 ingredients and with throughput up to 200, 400, 800 and 1300 kg/h. Its modular structure allows to increase the number of dosing stations even after the installation.

MORE INFORMATION

Full modular construction with 2, 3, 4, 5 or 6 ingredients available and DIY modularity.
Integral weigh downcomer hopper for extruder demand or gravimetric throughput control.
Load cell to sense variations in weight (no ultrasonic or capacitive sensor).

A cascade mixer provides excellent additive dispersion, including ingredients with different bulk densities or granule size.

Inclined screw feeders to improve metering accuracy and to prevent undesired dribble. They are driven by brushless motors with a wide range of speed.

Auger screws suitable for granules or free-flowing powders, extended throughoput range.

All parts that come into contact with the ingredients are made of satin stainless steel, or of food-grade materials or finishes.

The on-board control box does not require any floor space.

Standard supplied integrated refill valve, rotative-slide gate type (patent pending).

Easily accessible auger screws for quick and thorough cleaning, no tools required.

Drain spout for easy and quick hopper emptying.

Manual slide gate for auger screw inspection without hopper emptying.

Practical and easy access to all components.

Feed hoppers with wide cleaning window for visual level control and quick cleaning.

Standard weights kit for load cells calibration. Dedicated spots for placing the calibration weights, for the safety of the operators and easy of use.

CONTINUOUS BLENDER OPERATION

Precise continuous loss in weight control.
Weight loss of each ingredient is measured.
All ingredients are simultaneously metered through the auger directly into the integral weigh downcomer hopper, through the cascade mixer.
The weight of blended material in the downcomer hopper is continuously monitored to sense level variations caused by changes in extruder throughput or non-alignment between the feeders and extruder throughputs.
The feeders are individually controlled to achieve and maintain the preset blend ratios and to keep at the preset value the downcomer hopper level.
This means that the blending throughput is always aligned with that of the processing machine.

CASCADE MIXER ACTION

The ingredients are simultaneously metered in the right proportion directly into the cascade mixer where the different streams are mixed to form a homogenous blend with a perfect dispersion of additives.

On a mezzanine, to feed by gravity the supply hopper of the processing machine

Integrated loading system control (SmartConvey)

Fully automated loading system control, easy operated by the same interface used for gravimetric blenders. One or more vacuum pumps to serve more than one receivers whose association can be set through configuration. All receivers linked to the same pump are served in turn, according to a priority sequence automatically assigned. Loading active control to reduce ingredient at minimum on changeover
